Tyreek and I don't even think it's close. Two drops and a "game changing" fumble from the guy who is supposedly our game changer. No one else is close IMO.
I can't give it to Tyreek.
KC blanketed him all game with double and triple coverage (like we did to Kelce) to take him out of the equation (both teams were pretty successful in that).
One of those drops he had his facemask ripped at the line by Snead (not called by the refs, who let a lot go all game outside of the offense and defensive lines) which was why he was fractionally late to the ball and missed the catch.
As for the fumble, I'm with Dave that it was a horrible call by the refs.
